PHONOGRAPHIC CHIP REMQVER Fiied July 28, 1941 Eai.

My invention has for its primary object the provision of a novel and efiicient device for removing the chips cut by the recording stylus during the making of a phonographic record, whereby to prevent such chips from interfering with the stylus and thereby impairing or spoiling the record.

Another object of my invention is to provide a device of the character described which may be readily attached to phonographic recording apparatus in such manner that a rotary brush forming a part of the device is driven by the recording apparatus and operates to pick up the chips close to the stylus and retain them free of the record during the recording operation.

Another object of my invention is to provide a device of the character described wherein the brush carries a friction drive wheel for contact with the record as a simple and inexpensive drive means for the brush. 1 A further object is to provide a device of the character described wherein the brush is cylindrical and adapted to extend radially. from near the center to near the periphery of the record while the friction drive wheel therefor contacts the record or the other side of the center of the record whereby the bristles will sweep toward the stylus and thereby more effectively remove the chips from the record.

Yet another object is to provide a device of the character described wherein the brush is readily adjustable to regulate its brushing action so that it may be disposed in position to best clear the particular record of the chips cut by the stylus.

With the foregoing objects in view together with such other objects and advantages as may subsequently appear the invention is carried into effect as illustrated by way of example in the accompanying drawing in which:

Fig. 1 is a fragmentary top plan View of a chip removing device embodying my invention;

Fi 2 is a vertical sectional view of the device as shown in Fig. 1;

Fig. 3 is a sectional view taken on the line 33 of Fig. 2;

Fig. 4 is a sectional view taken on the line 4-4 of Fig. 2.

One embodiment of my invention as shown in the accompanying drawing includes a cylindrical brush 5 mounted on a shaft 6 rotatably supported at one end in a bearing lid on one end of a U- shaped supporting arm I. The other end of the arm is secured to a hinge B on an upstanding bracket 9 adapted to be secured by fastenings I0 to the cabinet or frame ll of phonographic recording apparatus A, parts of Which latter are shown in Figs. 1 and 2. The other end of the shaft 6 is supported in a bearing 6b on the hinge 8.

The recording apparatus includes the usual turntable I2 for a disk record such as the one 13 here shown, a recording arm l4 and a record-.

ing stylus [5 on said arm, the record being turned in a clockwise direction looking at Fig. 1.

The bracket 9 and arm 1 are mounted on so that the brush will extend radially from near the center of the record to a point near the periphery thereof on one side of the center of the record, with the bristles on the lower side of the brush in light contact with or closely spaced from the record. The support of the brush in this manner and its rotation are provided for by means of a friction drive wheel l6 fixed on the shaft 6 and resting on the record.

The diameter of this wheel and the height of the bracket determine the light contact or close spacing of the bristles relative to the record and provision is here made for vertically adjusting the brush to regulate the contact or near contact thereof with the record. This adjustment is provided for in the bracket 9 which as here shown consists of telescopic relatively adjustable sections l1 and I8 one of which is slotted as at l9. A bolt 20 is inserted through one of the sections and the slot I9 in the other section and has a thumb nut 2| adjustable thereon to hold the sections in adjusted position.

It should be noted that the shaft 6 extends to the opposite side of the center of the record from the side on which the brush is disposed and that the friction drive wheel I6 is on said extended part of the shaft so that it will contact the left side of the record while the brush is on the right side as seen in Fig. 1. This causes the bristles on the lower side of the brush to sweep toward the stylus and thereby pick up the chips cut by the stylus. Figs. 1 and 3 show typical chips 0 as cut by the stylus.

Preferably the brush is disposed beyond and close to the stylus so that it will pick up the chips as soon as they are cut by the stylus as indicated in Figs. 1 and 3.

The brush as shown in Fig. 3 has long bristles and the chips will be readily picked up and wound on and retained between the bristles so that the record is free of chips and the operation stylus will not be interfered with.

one side of the turntable so that records may be placed on and removed from the turntable. By having the brush in light contact or in closely spaced relation to the record and rotated against the direction of rotation of the record the bristles will sweep toward the stylus as clearly shown in Fig. 3 in such manner as to pick up and clear the record of all chips made by the stylus during a recording operation.

While I have shown and described a specific embodiment of my invention, I do not limit myself to the exact details of construction set forth, and the invention embraces such changes, modifications and equivalents of the parts and their formation and arrangement as come within the purview of the appended claims.

I claim:

1. In a chip remover for phonog'raphic recording apparatus, a rotary brush, means for supporting said brush with the bristles on the lower side thereof lightly contacting the recording surface of a disk record at a point adjacent the recording stylus of the apparatus, and drive means associated with said brush and adapted to be operated by said apparatus for rotating the brush so that said bristles will sweep toward the stylus and thereby pick up from the record the chips cut by the stylus, including a shaft extending from the brush and a friction drive wheel carried by the shaft and adapted to contact the record, said shaft intersecting the center of the record; said brush and drive wheel lying in axial alignment on opposite sides of the center of the record.

2. In a chip remover for phonographic recording apparatus, a rotary brush, means for supporting said brush with the bristles on the lower side thereof lightly contacting the recording surface of a disk record at a point adjacent the recording stylus of the apparatus, and drive means associated with said brush and adapted to be operated by said apparatus for rotating the brush so that said bristles will sweep toward the stylus and thereby pick up from the record the chips cut by the stylus, including a shaft extending from the brush and a friction drive wheel carried by the shaft and adapted to contact the record, said brush and drive wheel being aligned with and disposed on opposite sides of the center of the record.
